<h2>SYNOPSIS<a class="headerlink" href="#synopsis" title="Permalink to this headline">¶</a></h2>

<div class="section" id="description">
<h2>DESCRIPTION<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p><strong>llvm-as</strong> is the LLVM assembler.  It reads a file containing human-readable
LLVM assembly language, translates it to LLVM bitcode, and writes the result
into a file or to standard output.</p>
<p>If <em>filename</em> is omitted or is <code class="docutils literal"><span class="pre">-</span></code>, then <strong>llvm-as</strong> reads its input from
standard input.</p>
<p>If an output file is not specified with the <strong>-o</strong> option, then
<strong>llvm-as</strong> sends its output to a file or standard output by following
these rules:</p>
<ul class="simple">
<li>If the input is standard input, then the output is standard output.</li>
<li>If the input is a file that ends with <code class="docutils literal"><span class="pre">.ll</span></code>, then the output file is of the
same name, except that the suffix is changed to <code class="docutils literal"><span class="pre">.bc</span></code>.</li>
<li>If the input is a file that does not end with the <code class="docutils literal"><span class="pre">.ll</span></code> suffix, then the
output file has the same name as the input file, except that the <code class="docutils literal"><span class="pre">.bc</span></code>
suffix is appended.</li>
</ul>
</div>
<div class="section" id="options">
<h2>OPTIONS<a class="headerlink" href="#options" title="Permalink to this headline">¶</a></h2>
<dl class="docutils">
<dt><strong>-f</strong></dt>
<dd>Enable binary output on terminals.  Normally, <strong>llvm-as</strong> will refuse to
write raw bitcode output if the output stream is a terminal. With this option,
<strong>llvm-as</strong> will write raw bitcode regardless of the output device.</dd>
<dt><strong>-help</strong></dt>
<dd>Print a summary of command line options.</dd>
<dt><strong>-o</strong> <em>filename</em></dt>
<dd>Specify the output file name.  If <em>filename</em> is <code class="docutils literal"><span class="pre">-</span></code>, then <strong>llvm-as</strong>
sends its output to standard output.</dd>
</dl>
</div>
<div class="section" id="exit-status">
<h2>EXIT STATUS<a class="headerlink" href="#exit-status" title="Permalink to this headline">¶</a></h2>
<p>If <strong>llvm-as</strong> succeeds, it will exit with 0.  Otherwise, if an error occurs, it
will exit with a non-zero value.</p>
